CVE-2024-9048 represents a cross site scripting vulnerability within the y_project RuoYi framework version 4.7.9 and earlier. This vulnerability resides in the SysUserServiceImpl class, specifically within the Backend User Import functionality where the loginName parameter is improperly handled. The flaw occurs when user-supplied input is directly incorporated into web responses without adequate sanitization or encoding, creating an avenue for malicious actors to inject client-side scripts. The vulnerability manifests in the ruoyi-system/src/main/java/com/ruoyi/system/service/impl/SysUserServiceImpl.java file, making it a critical point of concern for applications utilizing this framework.
The technical exploitation of this vulnerability requires a remote attack vector where an attacker can manipulate the loginName argument to inject malicious JavaScript code. This type of vulnerability falls under CWE-79 which specifically addresses cross site scripting flaws in web applications. The attack complexity is classified as high due to the need for proper input manipulation and the requirement to bypass potential security measures that might be in place. The difficulty level of exploitation indicates that while the vulnerability exists, it requires skilled attackers with knowledge of the specific application structure to successfully implement. The fact that the exploit has been disclosed publicly increases the risk to systems that have not yet applied the available patch.
The operational impact of this vulnerability extends beyond simple script injection, potentially allowing attackers to perform session hijacking, deface web applications, steal sensitive user data, or redirect users to malicious sites. In the context of enterprise applications built on RuoYi framework, this vulnerability could compromise user authentication mechanisms and lead to unauthorized access to sensitive system resources. The backend user import functionality makes this particularly concerning as it often handles privileged user account creation and management operations. Attackers could leverage this vulnerability to escalate privileges or gain unauthorized access to user accounts within the system.
Security mitigation for CVE-2024-9048 requires immediate application of the provided patch identified by commit hash 9b68013b2af87b9c809c4637299abd929bc73510. Organizations should also implement comprehensive input validation and output encoding mechanisms to prevent similar vulnerabilities from emerging in other parts of the application. The ATT&CK framework categorizes this vulnerability under T1059.007 for scripting and T1566.001 for spearphishing with a link, highlighting the need for both defensive measures and user awareness training. Additional protective measures include implementing content security policies, regular security code reviews, and maintaining updated application security monitoring systems to detect potential exploitation attempts.
